STOVE.

SPECEFICATION forming part of Letters Patent No. 346,756, dated August 3,1886. Application filed January 23, 1885. Serial No. 153,763. (ModeL) Patented in France December 30, 1884, No.153,582.

To all whom it may concern:

Be itknown that we, KARL LEROH and KARL SEIDL, both citizens of the Austro-Hungarian Empire, residing at Gratz, Austria-Hungary, have invented new and useful Improvements in Stoves, of which the following is a specification.

This invention relates to improvements in closed stoves; and it has for its object an improved arrangement ofinternal fines, in which the hot gases circulate. The stove is moreover provided with a suitable number (say from two to twelve) of tubes or pipes, (say of clay oriron,) which are surrounded by the hot gases and admit the air of the apartment in which the stove is placed.

This inventionis represented in the accompanying drawings, in which Figure 1 is a sec tion on lineg g of Fig. 2. Fig. 2 is a section on line 2: e of Fig. 1. Fig. 3is a horizontal section on a; m, Fig. 2. Fig. 4 is a transverse section of the grate and its suppoi'tingslide.

The stove is of rectangular form, and has two partitions, c e, which extend from a short distance above the fire-box to a short distance below the top of the stove, are joined to the front and rear walls of the stove at each side, and joined together at their lower ends by a horizontal plate, a, which forms the top of the fire-box. These partitions are also connected to each other by a central partition, 6, reaching from their top to near the horizontal plate 0, thus dividing the central space between said partitions c 6 into a front and rear flue, ff, the rear one, f, being closed at the top bya plate, f. There are thus formed in the stove two lines, b b, one on each side, reaching from the fire-box a to the top of the stove. The front half of the partitions e c is cutoff at 1"" near the top, leaving openings g g, by which communication is had with a front central lluc, f, which at its bottom communicates, through opening with rear central flue, f, which opens at its top into stove-pipe h. The fire-box a is filled with fuel. The gases developed therein pass through suitable apertures, c c, and. in the direction of the arrows l 1 into upwardlyextending channels or flues b b. The gases following I the path shown by the arrows 2 2, next pass through openings {1 ginto and along a descending channel or flue, f, whence (following the path shown by the arrow 3) the gases flow into another rising flue, f, which leads the same to the chimney or a fine, 71, connected therewith.

The air-tubes hereinabove referred to may be of clay, pottery-ware, or cast-iron. They are set vertically in the fines, and are continually surrounded and heated by the hot gases. These tubes k is k 7-; draw in the air from the apartment in which the stove is set by horizontal passages, (in the direction of the arrows 5,) and allow it to escape by suitable openings at the top or in the lid of the stove.

Each store has two doors, which close hermetically. The upper one, on, serves for the introduction of the fuel; the lower one, a, closes the ash -pan or ash-pit, as usual. A movable grating, t, is supported on the frame .1, Fig. 4, and allows the fire -place to be readily cleaned.

For heating large rooms the air may be led into the horizontal air-passages It It 70* 76 from outside; and the lower part of these passages being surrounded by the flames, this air will be rapidly heated.

hat we claim is An air-heating stove of rectangular form, having a firebox, air-lines located in the corners and communicating at top and bottom with the air outside the stove, two side fiues, b 1), opening into the fire-box at their lower ends, and a front central ilue, f, opening on each side at the top into ilues b b, and a rear central tube, f, com 111 unicating at its bottom with the front central flue,f. and at its top with the escape or store pipe h, as and for the purpose set forth. I

In testimony whereof we have'hereunto set our hands in the presence of two subscribing witnesses.
